European alternatives to Dropbox

Nextcloud is the leading open-source alternative to cloud suites such as Google Workspace or Microsoft 365. Self-hosted or operated through a European provider, Nextcloud combines file sharing, calendar, contacts, video calls and office editing. Full data sovereignty is therefore central. The Community Edition (AGPLv3) is free for unlimited users – only the costs of your own server apply; Nextcloud Enterprise with support starts at around €69 per user per year (from 100 users).

Proton offers an entire ecosystem around encrypted communication: Mail, Calendar, Drive, Pass (passwords) and VPN. Its headquarters in Switzerland, end-to-end encryption and own server hardware in Switzerland and Germany make Proton one of the best-known privacy alternatives to Google and Microsoft. All apps are open source; Proton is ISO/IEC 27001 certified and has a SOC 2 Type II report. Proton Mail Plus starts at €4.99 per month (€3.99 with annual billing), the Proton Unlimited bundle at €12.99 per month.

Tresorit is an encrypted cloud storage service from Zurich that end-to-end encrypts files on the device itself (zero-knowledge). The keys stay with the user, so neither Tresorit nor third parties can read the content – a clear difference from conventional cloud storage. Since 2021 the company has been part of Swiss Post, which anchors it in Europe. Data is stored in European data centers (Switzerland, Ireland, the Netherlands), with the infrastructure running on Microsoft Azure. Tresorit is ISO/IEC 27001 certified. The personal plan starts at around €12 per month (billed annually); business plans are available per user for teams.
